ETSI standards group saw attempted takeover — PolicyTracker: the spectrum management newsletter
"... ETSI BRAN had been a group more or less in hibernation, until interest in using LTE-Unlicensed (LTE-U) in the US started to grow. This put the group at the centre of the coexistence debate between LTE-U and Wi-Fi."

A source tells us that “the Wi-Fi industry saw the European regulatory process as one means to stop LTE-U globally because 3GPP develops standards on a global basis for one area in the world. And so they said if we influence ETSI BRAN and the EN 301 893 standard, we can also have an impact on 3GPP. That’s exactly what has happened".

"Version 2.1.1. of the EN 301 893 standard was reviewed by member states, who duly returned comments. It was eventually approved. However, by the time it appeared in the Official Journal of the EU, where binding legal acts in Europe are recorded, it was listed alongside the older version (1.8.1.), saying that the the adaptivity clause of 1.8.1. was also applicable."

Industry Voices—Schoolar: Here comes unlicensed LTE … finally | FierceWireless, Aug 2017
T-Mobile launched commercial LTE-U networks across six cities in February. Furthermore, in June T-Mobile trialed LAA achieving 741 Mbps downlink, and plans to deploy it this year. Also in June, AT&T reported hitting 750 Mbps in its LTE-LAA trial, with its own plans for commercial launch by end of 2017. In the month of August, Verizon announced it is in the process of rolling out a commercial LTE-LAA network. The company also reported reaching 953 Mbps downlink speed in a recent trial. Outside of the U.S. (but in June as well), MTS of Russia has been trialing LTE-LAA. For these, and other operators, LTE using unlicensed spectrum helps get them to 1 Gbps LTE.

MulteFire Alliance wraps up Release 1.0 specification | FierceWireless Jan 2017
"The MulteFire Alliance is celebrating a big milestone with the completion of its Release 1.0 specification. Based on 3GPP Releases 13 and 14, Release 1.0 defines how LTE operates in unlicensed and shared spectrum, two places that wireless operators and others increasingly will be using spectrum."

"MulteFire enables any entity, regardless how small they are, to operate their own LTE network in unlicensed spectrum. "

LTE vs. Wi-Fi Simulations: The output is only as good as the input | Joey Padden | Pulse | LinkedIn
The punchline seems to be

I understand and appreciate the engineering desire to strictly adhere to the spectrum management principle that the government should not regulate unlicensed spectrum uses. Focused narrowly on spectrum management doctrine, unlicensed is supposed to be the home of permission-less innovation. But in my mind LAA/LTE-U pose a broader public policy question. Stated simply it is:

“Should private wireless carriers that want to save money by moving data traffic from expensive licensed spectrum to free unlicensed spectrum be allowed to interfere with public Wi-Fi used by millions of consumers and by important institutions and infrastructure in our society?”

To me, the broad public interest answer to this question is self-evident - “no”.

Another criticism is limited scope:

There are two primary issues with this analysis, firstly the papers present this work as covering “a large design parameter space” when in fact these simulations cover a narrower parameter space than that used in the 3GPP simulation efforts. Areas not studied in this analysis include: <long list of stuff>

He goes on to critique various other aspects, including “These simulations assume throughput as the only metric. But, latency is a first order performance metric.”

Samsung trying to stay neutral in LTE-U fight | FierceWireless - Sep 2016
"Even though Samsung was one of the early vendors to collaborate on LTE-U, it’s now taking more of a neutral stance on the technology, letting operators take the lead on the controversial deployment that uses unlicensed spectrum.

While Samsung has developed LTE-U small cells that are in trial with operators, Samsung is also the largest Wi-Fi purchaser in the world, said Alok Shah, VP of strategy for BD and marketing, in an interview with FierceWirelessTech at CTIA Super Mobility 2016."

Mobile operators to shift from "pure Wi-Fi" to unlicensed services tied to LTE, says report — PolicyTracker: Jul 2016
"At least 90 per cent of mobile data will be carried over unlicensed bands anchored to variants of LTE by 2020, according to a report from research firm Mobile Experts. But it's still not clear whether there's any real need to aggregate unlicensed with licensed spectrum.
The report, "Carrier Wi-Fi and LTE-U 2016," predicts a "decisive transition" from "pure Wi-Fi" to the tying of unlicensed services to LTE in various ways."
"Around 80 per cent of mobile data is carried over Wi-Fi today, but that figure will rise to at least 90 per cent by 2020, said Mobile Experts analyst Joe Madden."
"What's really needed is "close cooperation between 3GPP, IEEE and regulators to develop a consensus on rules for hybrid band sharing and aggregation (fixed/mobile converged networks that combine licensed and licence exempt band use)," said Horvitz. And if not rules, he added, then there should at least be principles concerning technical and coexistence fairness issue"

The Wi-Fi Alliance hosted another coexistence workshop last Wednesday in San Jose, California, where stakeholders were given status updates, including the expectation that a final test plan is likely to slip into September, according to Kevin Robinson, vice president of marketing at the Wi-Fi Alliance."

Globalstar gets positive vibe from Public Knowledge's letter to FCC - FierceWirelessTech

The letter from Public Knowledge on Globalstar's proposal to use the 2473-2495 MHz band for terrestrial low power services (TLPS) also suggested the commission to use it as a chance to reframe the commission's public interest analysis "to stress the importance of unlicensed as equal to, not subordinate to, licensed spectrum."" "Feld also in recent weeks has called for the commission to address the LTE-U controversy by issuing a declaratory ruling that Section 333 applies not only to deliberate jamming, but that the commission should interpret the word "willingly" as meaning deploying technology that one knows will create unacceptable levels of interference. He notes that other blogs, including those by the Electronic Frontier "

Meanwhile, the National Cable & Telecommunications Association, speaking for many cable companies that have their own Wi-Fi networks, hit back hard against Qualcomm. In an FCC filing made public on Wednesday, NCTA said that Qualcomm has not engaged in meaningful collaboration with the unlicensed community, and that its proposals thus far on LTE-U/Wi-Fi coexistence are not fair or equitable.

A conversation with Ziemowit Neyman, RAN Assistant Director, and Seppo Hämäläinen, RAN and SON Tools Assistant Director, Ooredoo “Any Wi-Fi access point operating in the same spectrum band as LTE-U is actually in the price range of hundreds of dollars, while any LTE-U small cells, working in the same spectrum, are expected to be in the price range of thousands of dollars. There is a huge price-point difference, and the question is whether operators will be willing to spend more resources for the LTE-U capabilities, instead of using Wi-Fi access points,” Neyman said.

" ** "LTE-U is for release 10, 11 and 12, but it becomes LTE-LAA when release 13 is ratified. The inclusion of LBT is the differentiator." ** "... LTE-U brings about three main advantages: First is better propagation yielding better coverage and throughput. The range of an LTE-U small cell would largely mirror its licensed anchor, but Qualcomm says its tests show a 1.5 to two times larger radius for LTE-U downlink when compared to WiFi. Second, the operator only has to manage one network because WiFi is treated as just another band to aggregate under their licensed bands. Third, ... quality of service will be much higher than on WiFi alone."
